Description

Technical Field

[0001] The present invention relates to the technical field of preparing carbon black from coal tar, and more specifically, to a gas-liquid-solid three-phase feeding device. Background Art

[0002] The main component of carbon black is carbon element, which is a carbon material formed by pyrolysis or partial combustion of many gaseous, liquid and solid carbon-rich hydrocarbon substances under strictly controlled inert or oxygen-deficient environments. It is also the largest-scale nano-carbon material in current industrial production.

[0003] Coal tar is an important product of coal pyrolysis and an important raw material for producing high-quality fuels or chemicals. However, coal tar has a relatively high density, generally in the range of 1160 - 1220 g / cm 3 During the process of preparing functional carbon materials by pyrolyzing coal tar, a series of solid catalysts insoluble in coal tar need to be added to directionally regulate the physical and chemical properties of the carbon materials. To solve the problems that the solid catalysts are insoluble in coal tar, and the high viscosity of coal tar leads to wall sticking and relatively large droplet diameters, etc., the present invention proposes a multiphase uniform feeding device, which includes a liquid atomizing spray gun, a reaction gas uniform air distribution cavity and a solid catalyst feeding pipe. This device first applies a high-viscosity liquid atomizing device to the coal tar pyrolysis process and synergistically acts with the solid catalyst and gas feeding, which is a breakthrough research on the device required for preparing functional carbon black from coal tar under the action of a catalyst.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

At the same time, it should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0025] An embodiment of the present invention provides a gas-liquid-solid three-phase feeding device for raw material supply during the preparation of carbon black from coal tar, including a gas feeding structure 1, a liquid atomizing feeding pipe 2 and a solid feeding pipe 3. The gas feeding structure 1 includes a air distribution chamber 11 and an air outlet end 12. The air outlet end 12 is located at the bottom of the air distribution chamber 11. The liquid atomizing feeding pipe 2 and the solid feeding pipe 3 penetrate through the air distribution chamber 11, and the first discharge end 21 of the liquid atomizing feeding pipe 2 and the second discharge end 31 of the solid feeding pipe 3 are arranged on the same end surface as the air outlet end 12, and the air outlet radiation range of the air outlet end 12 covers the first discharge end 21 and the second discharge end 31.

[0026] Combined with Figures 1 to 4 As shown, in the embodiment of the present invention, by arranging the liquid atomizing feeding pipe 2 and the solid feeding pipe 3 to penetrate through the air distribution chamber 11 of the gas feeding structure 1, the gas feeding structure 1, the liquid atomizing feeding pipe 2 and the solid feeding pipe are integrally arranged. While the structure is compact, simultaneous feeding of gas-liquid-solid three-phase raw materials can be achieved; in the embodiment of the present invention, the first discharge end 21 of the liquid atomizing feeding pipe 2 and the second discharge end 31 of the solid feeding pipe 3 are also arranged on the same end surface as the air outlet end 12, and the air outlet radiation range of the air outlet end 12 covers the first discharge end 21 and the second discharge end 31, so that the liquid raw material and the solid raw material are surrounded by the gaseous raw material, providing favorable conditions for the full mixing of the gas-liquid-solid three-phase raw materials, effectively improving the phenomenon that the solid catalyst is insoluble in coal tar and the gas-liquid-solid three-phase reactants are not evenly mixed during the process of preparing functional carbon materials by pyrolysis of coal tar, and at the same time preventing the reaction products from polluting the liquid raw material and the solid raw material, and improving the quality of the carbon black product.

[0027] In the existing process of preparing carbon black from coal tar, raw materials such as reaction gas, liquid highly viscous coal tar, and solid hydrodemetallization catalyst need to be fed into the reaction equipment separately. However, the existing feeding devices can only feed the gas-liquid-solid three-phase raw materials separately in time or feed the two-phase raw materials simultaneously, and cannot achieve the effect of feeding the gas-liquid-solid three-phase raw materials simultaneously, which easily causes the phenomenon of uneven mixing of the gas-liquid-solid three-phase raw materials. In this embodiment, while realizing the synchronous feeding of the gas-liquid-solid three-phase raw materials, considering uniform mixing, the air outlet radiation range of the air outlet end 12 covers the first discharge end 21 and the second discharge end 31. When feeding simultaneously, the liquid raw material and the solid raw material will be impacted and driven by the gaseous raw material, thereby increasing the contact area and achieving the effect of improving the mixing effect.

[0028] Specifically, the air distribution cavity 11 of the gas feeding structure 1 is a cylindrical cavity. The solid feeding pipe is vertically penetrated and arranged at the central position of the cylindrical cavity. The upper end is the solid raw material feeding end, and the lower end is the second discharge end 31 of the solid raw material. The liquid atomization feeding pipe 2 is arranged close to the solid feeding pipe to facilitate the mixing of the liquid raw material and the solid raw material. The gas feeding structure 1 further includes an air inlet, and the air inlet is communicated with the air distribution cavity 11. After the gaseous raw material enters the air distribution cavity 11 through the air inlet, it is blown out through the air outlet end 12 and blows towards the liquid raw material and the solid raw material flowing out simultaneously, realizing the uniform mixing of the three phases by using the airflow drive and the inertia force of the liquid raw material and the solid raw material.

[0029] In some specific embodiments, the air outlet end 12 includes an air distribution plate 121, and a plurality of air distribution holes 122 are provided on the air distribution plate 121. The plurality of air distribution holes 122 are arranged around the first discharge end 21 and the second discharge end 31.

[0030] The air distribution plate 121 in this embodiment, as Figure 3 shown, a plurality of air distribution holes 122 are provided on the air distribution plate 121, and the plurality of air distribution holes 122 are arranged evenly in a certain rule. The second discharge end 31 of the solid feeding pipe is located at the center of the shape formed by the arrangement of the plurality of air distribution holes 122, and the first discharge end 21 of the liquid atomization feeding pipe 2 is arranged close to the center of the shape formed by the arrangement of the plurality of air distribution holes 122. In some embodiments, the air distribution holes 122 can be arranged obliquely or vertically, which is beneficial to adjusting the air outlet flow direction according to needs and making full use of the driving effect of the gaseous raw material to fully mix the three phases.

[0031] In some specific embodiments, the liquid atomization feeding pipe 2 includes a sleeved outer pipe 22 and an inner pipe 23. The inner pipe 23 is used to transport the liquid raw material, and the outer pipe 22 is used to transport the gas. The cross-section of the outer pipe 22 gradually decreases in the direction towards the first discharge end 21 to atomize the liquid raw material by gas friction.

[0032] Specifically, in order to enable the liquid raw material to come into full contact with the other two-phase raw materials, in this embodiment, the structure of the liquid atomizing feed pipe 2 is optimized. The outer pipe 22 conveys gas, and by changing the cross-section of the outer pipe 22 near the port of the first discharge end 21, the direction of gas flow is changed and the gas flow rate is increased. At the same time, high-speed gas can also be conveyed into the outer pipe 22 through the air inlet of the outer pipe 22. When the cross-section of the outer pipe 22 gradually decreases in the direction towards the first discharge end 21, the high-speed gas will blow towards the port of the inner pipe 23. When droplets of liquid flow out from the port of the inner pipe 23, the high-speed gas impacts the droplets, dispersing the droplets to form a misty liquid. Continuous high-speed gas impact and friction cause the flowing liquid raw material to be continuously friction atomized. In order to make the atomization more sufficient, the cross-section of the inner pipe 23 can be adjusted so that the cross-section of the inner pipe 23 also gradually decreases in the direction towards the first discharge end 21, controlling the flow rate of the liquid raw material at the port and reducing the flow rate of the liquid raw material at the port, so that the gas can fully atomize the liquid raw material. In some embodiments, as Figure 4 shown, the liquid atomizing feed pipe 2 can be replaced with an air atomizing spray gun,

[0033] The special internal structure of the air atomizing spray gun can evenly mix the liquid raw material and the compressed gas, generating a spray with fine droplet sizes. Therefore, it can effectively alleviate problems such as the wall sticking phenomenon of highly viscous fluids such as coal tar, poor liquid atomization effect, and large droplet volume, and has outstanding advantages especially in the aspect of uniform feeding of highly viscous fluids. As Figure 4 shown, in this embodiment, the liquid raw material sprayed by the air atomizing spray gun can be in a wide-angle circular spray pattern, having a wide flow rate range, which can increase the contact area with the solid catalyst and the atmosphere, enabling the coal tar to be fully pyrolyzed. It should be noted that when used for preparing carbon black from coal tar, the solid raw material is the solid catalyst, and the gaseous raw material is the protective gas during the reaction, providing a gas atmosphere.

[0034] In some specific embodiments, there are two liquid atomizing feed pipes 2, and the two liquid atomizing feed pipes 2 are arranged obliquely relative to each other, and the two first discharge ends 21 are arranged close to each other so that the flowing liquid raw materials form a counterflow.

[0035] Combined with Figure 1 shown, on the basis of the previous embodiment, this embodiment is further optimized. The first discharge ends 21 of the liquid atomizing feed pipes 2 are arranged opposite to each other. In this way, the ejected viscous liquid will collide and squeeze violently due to the counterflow. The large droplets will break due to the huge impact force, and the small droplets will combine under the action of the force to form larger droplets, making the droplet particle size tend to be consistent, which is beneficial to the homogenization of the droplets; at the same time, under the action of the counterflow force, the occurrence of liquid wall sticking can also be reduced.

[0036] Specifically, when the two jets collide with each other, the small droplets formed under the combined action of various forces such as viscous force and surface tension will combine with each other to form larger droplets. The larger droplets have a certain velocity, which endows the droplets with better penetration ability and anti-drift ability. At the same time, through testing, when the included angle of the liquid atomization feeding pipe 2 is 30°, the outer edge of the atomization angle is parallel to the reactor pipe, improving the phenomenon of tar sticking to the wall.

[0037] In some specific embodiments, the included angle between the two liquid atomization feeding pipes 2 is 10° - 90°. This is beneficial to forming a better counter-jet effect. Preferably, when the included angle between the two liquid atomization feeding pipes 2 is 30°, the atomization effect is the best, which can uniformly atomize high-viscosity liquids, increase the contact area between the high-viscosity liquid and the solid catalyst, and enhance the pyrolysis effect.

[0038] In some specific embodiments, the solid feeding pipe 3 is arranged between the two liquid atomization feeding pipes 2, and the second discharge end 31 of the solid feeding pipe 3 is arranged towards the counter-jet surface formed by the liquid raw materials flowing out from the two first discharge ends 21.

[0039] In this embodiment, the solid raw materials flowing out from the second discharge end 31 of the solid feeding pipe 3 pass through the counter-jet surface formed by the liquid raw materials flowing out from the first discharge ends 21, which can enable the solid raw materials to make full contact with the atomized liquid raw materials, thereby enhancing the pyrolysis effect.

[0040] In some specific embodiments, it further includes a cooling structure 4, and the cooling structure 4 is arranged around the side wall of the air distribution chamber 11.

[0041] Specifically, as Figure 1 and Figure 2 shown, the cooling structure 4 in this embodiment includes a cooling channel and an air inlet and an air outlet connected to the cooling channel. The cooling channel is arranged around the side wall of the air distribution chamber 11 and is in close contact with the air distribution chamber 11. The contact surface between the air distribution chamber 11 and the cooling channel is provided with a special sealing and heat-exchange material to control the airtightness and heat-exchange effect. The air inlet and the air outlet are used to introduce or discharge low-temperature media to cool the feeding device by means of convective heat transfer and heat conduction, so as to avoid damage to the device due to high temperature, improve the service life, and at the same time reduce the temperature of the upper operating platform, facilitate the replacement of materials, and improve the operation safety.

[0042] In some specific embodiments, a diffuser 32 is provided at the bottom of the second discharge end 31. The diffuser 32 includes a diffusion surface, and the diffusion surface is arranged towards the discharge end of the solid feeding pipe 3, and is used to evenly eject the solid raw materials flowing out from the second discharge end 31 to the surroundings.

[0043] Specifically, a diffuser 32 for evenly spreading the solid raw materials is provided at the bottom of the second discharge end 31 of the solid feed pipe 3. After the solid raw materials flowing out from the second discharge end 31 fall and impact on the diffusion surface of the diffuser 32, by using the reaction force generated during the falling impact, the solid raw material particles will be ejected following the angle formed by the tangent direction of the impact point on the diffusion surface and the incident angle. When the circumferential direction of the diffusion surface is uniformly provided with an inclined surface that slopes outward as the falling impact surface of the solid raw materials, the ejection will occur in the direction of the ejection angle around, and evenly contact with the atomized liquid raw materials, thereby increasing the contact area between the highly viscous liquid and the solid catalyst and enhancing the pyrolysis effect. Preferably, the diffusion surface can be an upright conical surface or other shapes with diffusion functions.

[0044] In some specific embodiments, the diffuser 32 is an arc-shaped diffuser 32. The arc-shaped ends of the arc-shaped diffuser 32 are connected to the second discharge end 31, and the plane where the arc-shaped ends are located is perpendicular to the plane where the two liquid atomizing feed pipes 2 are located.

[0045] Combined Figure 1 As shown in the figure, the diffuser 32 in this embodiment is preferably an arc-shaped diffuser 32. When the solid raw materials fall and impact on the diffusion surface, due to the reaction force and the angle of the arc surface, the solid raw materials can form a uniform diffusion, preventing the accumulation of solid raw materials in a certain direction, which is not conducive to the uniform contact with the atomized liquid raw materials. The plane formed by the connection of the arc-shaped ends of the arc-shaped diffuser 32 and the second discharge end 31 in this embodiment is set perpendicular to the plane where the two liquid atomizing feed pipes 2 are located in consideration of the full contact with the atomized liquid raw materials, preventing the connection part from blocking the diffusion of the solid raw materials towards the direction of the liquid atomizing feed pipes 2.

[0046] In some specific embodiments, a sealing structure is further included, and the sealing structure is arranged at the connection position between the liquid atomizing feed pipe 2 and the air distribution chamber 11.

[0047] The liquid atomizing feed pipe 2 in this embodiment penetrates through the air distribution chamber 11. Since there is flowing gas in the air distribution chamber 11, good sealing performance needs to be ensured. Setting a sealing structure at the connection position between the liquid atomizing feed pipe 2 and the air distribution chamber 11 can ensure reliable sealing at the connection. Similarly, a sealing structure can also be set at the connection between the solid feed pipe 3 and the air distribution chamber 11 to improve the sealing performance of the air distribution chamber 11. The sealing structure can be diverse, and materials and structures that can ensure the sealing performance at the connection can be utilized. Preferably, it can be a rubber sealing ring or sealing strip.

[0048] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the protection scope of the present invention.
